This is one of the gotchas of if/elif chains and I discuss it in
my branching topic in the tutorial.
Basically you have to sequence the tests to that you gradually
filter out the ones you want.

return exits the construct so you will always exit here or
on the line above, you need to move this test to the bottom.
I'd suggest a sequence like:
> if num < 7:
> elif num <16:
> elif num < 26:
> elif num >= 16:
> elif num >= 7:
> else:
> return 'Senior'
But mixing test types makes it really hard to do reliably.
Its better to combine tests like this:
if num < 7: retiurn 'Freshman'
elif 7 <= num < 16: return 'Sophomore'
elif 16 <= num < 26: return 'Junior'
else: return 'Senior'
Which I think is what you are tring to do?
If thats too confusing you can use an explicit and test:
if num < 7: ...
elif (num >= 7) and (num <16): ...
etc...
The above is simply a shorthand way of writing the combined tests.
